My proposal is on the reserve list. What does that mean?

If the available budget is too small to fund all proposals that reached the qualifying score in the evaluation round, some proposals may be put on a reserve list – of proposals that may be offered funding if a higher-scoring project does not go ahead or additional funds become available.
This may take up to one year until you are informed if your proposal will be still be funded or not. Experience from recent years shows that no more than 5 proposals (depending on the panel!) might be funded from the reserve list. However, it is impossible to foresee or give a valid estimation about the chances for funding.
